In-Form is used to supply, at the boundaries of a 2D box with x
horizontal and y vertical, boundary conditions of pressure and
velocity which correspond to an ideal-fluid travelling gravity
wave in moderately deep water.

Within the box, the pressure and velocity are computed from the
momentum and energy equations in the usual way.

It is interesting to compare their values with those
corresponding to the ideal-fluid wave, namely: pdif, udif and vdif

If OBSTCL=T, an obstacle appears on the the sea-bed.
If STRA  =T, the stresses and strains in it are computed
